Abstract

The reason for writing this article is to deepen in two concepts that we believe are fundamental in the build-up of a new Biochemistry and therefore a new era in medicine, because allow us a better understanding of the biology of the eukaryotic cell, and specifically for this chapter, of the muscle cell. The first one is the theoretical concept of intracytoplasmic cell´s common energy levels proposed by Prof. Szent-Gyorgyi in the first half of the past century and the second one the surprising fact that the muscle relaxation involves higher levels of chemical energy than the muscle contraction stage, which presupposes a reduction in the level of the energy. The hitherto intrinsic chemistry of melanin to dissociate the water molecule fits and finally explains perfectly the teachings of Prof. Szent-Gyorgyi, and allows, at last, to move them to clinical practice. The physiology of contraction and muscle relaxation has tried to explain based on glucose and ATP as main sources of muscle power, but has not been achieved satisfactorily despite notable efforts of researchers. And proof of this is that muscle problems, even the most common, will have not been able to improve in clinical practice. The finding about the unsuspected function of melanin to generate chemical energy dissociating the water molecule, opens a new and promising panorama in the muscle cell biology. Which is complemented by our recent finding that molecules which contain the Heme group, such as chlorophyll, Myoglobin, hemoglobin, CYT P450, and the bilirubin, are also able to dissociate the water molecule but, unlikely melanin; irreversibly.
